Involuntary extension of the "normal" leg occurs when flexing the contralateral leg against resistance. To perform the test, the examiner should hold one hand under the heel of the "normal" limb and ask the patient to flex the contralateral hip against resistance (while the patient is supine), asking the patient to keep the weak leg straight while raising it.

Lowenberg's sign is a clinical sign found in patients with deep vein thrombosis of the lower leg. The sign is positive when pain is elicited rapidly when a blood pressure cuff is placed around the calf and inflated to 80 mmHg .

Gordon's sign is a clinical sign in which squeezing the calf muscle elicits an extensor plantar reflex. It is found in patients with pyramidal tract lesions , and is one of a number of Babinski-like responses .
After many examples of false-positive Homans' signs were reported, Homans redefined it in 1944, stating that "discomfort need have no part in the reaction", and that increased resistance, involuntary flexure of the knee or pain in the calf upon forced dorsiflexion should be considered positive responses.

The Thompson test (also called Simmonds' test or Simmonds-Thompson test) is used in lower limb examination to test for the rupture of the Achilles tendon. [ 1 ] [ 2 ] The patient lies face down with feet hanging off the edge of the bed.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
